It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-17023 and fix it if it is affected.\n\nWhat it is: CVE-2020-17023 is a high-severity code injection vulnerability in Microsoft Visual Studio Code, published on 16 Oct 2020. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-17023 in the wild and no public exploit code.\n\nAffected product: Microsoft Visual Studio Code. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2020-17023/ (Markdown: https://insights.sbomify.com/CVE-2020-17023/index.md)","id":"CVE-2020-17023","markdown":"https://insights.sbomify.com/CVE-2020-17023/index.md","name":"CVE-2020-17023","record":{"aliases":["GHSA-vwrg-gm47-cm4h"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Visual Studio Code","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening a malicious package.json file in Visual Studio Code.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"visual_studio_code","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C","version":"3.1"},"cwes":[],"description":"\u003cp\u003eA remote code execution vulnerability exists in Visual Studio Code when a user is tricked into opening a malicious 'package.json' file.
